The erc utility is currently a simple interface to the query metadata tags from the ERC vocabulary.
Its one sub-command,
get,
receives zero or more tag arguments,
which are either numbers,
element names,
or regular expressions.
Given one or more tags,
it prints the corresponding ERC element name,
a tab,
and its semi-numeric code,
one per line.
With no arguments,
get prints all known names in hash table order (which tends to look random).

A tag given as a non-negative integer,
possibly preceded by a letter,
will usually be looked up as a semi-numeric code.
If the tag looks like a regular expression,
it will be used to search among element names.
Otherwise the tag will be looked up as an element name.
The return status will be 1 if any requested code is not known.

This is beta-level software.
To create and convert ERC records,
see the anvl(1) command and the File::ANVL and File::OM Perl modules.
